Outline of Final Research Achievements

We developed the groundwater exploration technique with the aim of increasing wells with the shallow groundwater level and sufficient water volume for nomadic people in arid and semi-arid region. As a result, the following three points were clarified. 1. If the groundwater aeration sound is about the same as the detection limit, it can be assumed that there is no groundwater resource available for nomadic people at that point. 2. If shallow groundwater is present and minute flow is occurring even in semi-arid areas, the groundwater level can be estimated with high precision by groundwater aeration sound. 3. When there are groundwater paths arise from geological structure, discontinuity with surrounding groundwater aeration sound occurs, so the geological structure such as fault can be explored.
